Answer this question truthfully
### Question: What causes Ventricular tachycardia?
### Response: Ventricular tachycardia is a pulse rate of more than 100 beats per minute, with at least three irregular heartbeats in a row.
The condition can develop as an early or late complication of a heart attack. It may also occur in patients with:
Cardiomyopathy Heart failure Heart surgery Low magnesium levels Low potassium levels Myocarditis Valvular heart disease
Ventricular tachycardia can occur without heart disease.
Scar tissue may form in the muscle of the ventricles days, months, or years after a heart attack. This can lead to ventricular tachycardia.
Ventricular tachycardia can also be caused by:
Anti-arrhythmic medications Changes in blood chemistry (such as a low potassium level) Changes in pH (acid-base) Lack of enough oxygen
Torsade de pointes is a form of ventricular tachycardia that is often due to congenital heart disease or the use of certain medications such as clarithromycin, erythromycin and claritin.
